VApplication ledApril'Z, 1914. .-Seria1No. 829,089.

To all whom 'it may concern:

"Be it known that I, IRAV A. CHURCH, a citizen of the United States ofAmerica, residing at Ontario, in the county of San Bernardino and Stateof California, have invented certain new and useful Improvements inBench-Dogs, of which the'following is a specification.

This invention relates to wood-working and more particularly to a benchdog and saw clamp designed to automatically clamp the material to beworked or operated upon.

The objects of the invention are z-to provide a device of this characterwhich will be simple and cheap in construction; efficient in operation;andwhich will beadjustable to material of various sizes; also to providea simple and eiiicient saw clamp which may be readily swung out of theway, when not in use and which, when in position for use, will Contactwith operating means connected to said dog.

With these and such other objects in view as may hereinafter more fullyappear, my invention consists in the novel arrangement vand constructionof parts set forth in the specification, more particularly. pointed outin the claims, and which are shown in the accompanying drawings,wherein:-

Figure 1, is a plan view of the device. Fig. 2, is a side elevationthereof showing the saw clamp in operative position. Fig. 3, is a frontelevation. Fig. 4, is a transverse vertical sectional view taken on theline 4-4 of Fig. 1. Fig. 5, is a detail sectional view of the resilientcatch.

Referring to said drawings by numerals t-a suitable bifurcated base ofany convement and preferred material, is provided, along the outer edgeof the reduced arms 1, thereof, with flanges 2; the upper surfaces ofsaid flanges being level with the surface of the cross bar 3 of saidbase. Secured upon said base in any suitable manner, as by the screws 4,is a bifurcated cover 5, the inner corners of the arms of which aresupported on blocks or rests 6; which may be integral with the cover, orthe base, or may be separate pieces, as preferred.

As will be readily understood from the foregoing, open spaces 7, areformed between the arms 1 and the cover 5. Within the spaces 7 arepivotally mounted; in any convenient and preferred manner, as by thepins 8; levers 9, provided with suitable resilently actuated catches 10adapted to enter the sockets 11, formed .in the ends of arms 1, topermit of adjustment of said levers. Pivotallv mounted on saidlevers, asby means of the pins 12, are dogs 13, of the usual and ordinary form,provided with the angularly disposed gripping shoes 14, be-

L tween which the materialv is held when the end of such material comesin contact with', and expands the fingers 15 of said dogs.

A curved spring 16, is suitably mounted on the cross bar 3 of the base,the Ycurved ends thereof contacting the fingers 15 of the dogs andretaining the same in place :when not in use.

by means of arod 17 passing through `a suitable bore formed in saidbase, is a saw clamp provided with arms or end-supports 18, thedownwardly projecting portions of which are suitably apertured toreceive said rod 17. The side supports 18 have their free ends angularlydisposed as at 19, and

carry suitably fastened between said angularly disposed ends a rod 20,to form one jaw of a saw gripping device. Arms 21 are pivotallyconnected to the side supports 18, through the ears 22 which are formedintegral with said arms 21, said pivotalconnection being accomplishedthrough the reduced ends of a rod 23 entering suitable apertures fortheir reception. The object of said rod being, to form not only apivotal connection but also a support and brace for the device. The arms2l are provided with the angularly disposed ends 24, complemental to theaforesaid ends 19, betweenwhich is suitably fastened the rod 25, formingthe other jaw of the saw gripping device. Between the lower ends of saidarms 21 is fastened a rod 26. Rod 26 is engaged by the grooved end 27,of a bar or link 28, the other end 29 of which is globular in form andadapted to rest in a socket 30 formed in one of the dogs 13.

As will be readily understood, when the saw clamp is in operativeposition, the insertion of a piece of material between the dogs willcause the link 28 to be forced outwardly against the bar'26, therebyclamping the saw 1n place between the rods 2O and 24. The dogs operatein the usual manner of such devices, their position being 'regulated bymoving the ends of levers 9 toward or away from each other of materialmay demand. The resilient catch may be of any well known and usual asthe size v 70 Pivotally mounted on one side of base' 3,

design but, as here shown, it consists of a thumb cap l0 provided with apin 3l encircled by a collar or flange 32. Pin 3l extends through asuitable aperture formed in a cup shaped member 83, and is encircled bya coiled spring 34 interposed between the collar or {iange 32 and thecup shaped member. Member 33 is suitably secured to the lever 9 near theoperative end thereof.

lThe device is to be attached, in any suitable manner, to a work bench.

Having described my invention, what I claim as new and desire to secureby Let ters Patent, is

l. In a device of the character described,

a suitable base, arms pivotally secured to said base, dogs pivotallysecured to said arms, a saw-clamp hinged to one side of said base, andmeans interposed between one of said dogs and said clamp whereby saiddog may operate said clamp.

2. In a device of the character described, a suitable base, armspivotally secured to said base, dogs pivotally secured to said arms, asaw-clamp hinged to said base, means interposed between one of said dogsand said clamp whereby said dog may operate said clamp, and means foradjusting said arms toward and away from each other.

3. In a device of the character described, a suitable base, armspivotally secured, at one of their ends, to said base, means carried bythe other ends of said arms for engaging spaced apertures in said basefor securing said arms in desired positions, dogs pvotally secured tosaid arms, a saw-clamp secured to said base, means interposed betweensaid clamp and one of said dogs whereby said dog may operate said clamp,and means for swinging said saw-clamp below the bench, when not in use.

In testimony whereof I hereunto afix my signature in presence vof twowitnesses.
